Systems and methods described herein bring a 5G standalone-capable end device back into 5G service to leverage the 5G network's data capacity as soon as a VoLTE call is over. A network device receives a fallback connection, for a 5G New Radio (NR) standalone-capable end device, from a second network to the first network to support a voice call on the end device, wherein the fallback connection supports a voice-over-LTE call. The network device detects an end of the VoLTE call and initiates, in response to the detecting, a handover of the end device back to the second network, wherein the initiating occurs while the end device is in a radio resource control (RRC) connected mode.

A device may receive a signal from a wireless station; and determine a network-permitted Time Division Duplex (TDD) uplink duty cycle based on the signal. If the determined network-permitted TDD uplink duty cycle is greater than a maximum allowable TDD uplink duty cycle for the device, when the device performs TDD uplink transmission after receiving a scheduling grant from the wireless station, the device may decrease the TDD uplink duty cycle of the device or may decrease a time-average transmission power of the device.

A user device provides, to a network, information associated with the user device, and receives, from the network, a multi-bit network indication that indicates access technologies, services, and network capabilities provided by the network. The user device determines whether the user device is in a home network or a visited network based on the multi-bit network indication. The user device passes bits of the multi-bit network indication to an upper layer when the user device is in the home network or passes a portion of the bits of the multi-bit network indication to the upper layer when the user device is in the visited network. The user device receives a selection of one of the access technologies, the services, or the network capabilities, and receives, from the network, the one of the access technologies, the services, or the network capabilities for the user device based on the selection.
